The German version of the Stroke Upper Limb Capacity Scale: Translation, cross-cultural adaption and evaluation of its psychometric properties.

OBJECTIVE: To investigate the psychometric properties of a newly developed German version of the Stroke Upper Limb Capacity Scale (SULCS). DESIGN: Prospective cohort study. SETTING: Neurorehabilitation clinic. SUBJECTS: Patients after stroke (n = 50) with moderate to severe upper limb hemiparesis undergoing inpatient rehabilitation. INTERVENTION: Not applicable. MAIN MEASURES: The SULCS was administered twice by two different raters on the first day of assessments and another time the day after. Additionally the Fugl-Meyer-Assessment, Action Research Arm Test and the Box and Block Test were conducted. Three and six weeks later, the SULCS, Fugl-Meyer-Assessment and Box and Block Test were repeated. Floor and ceiling effects were analyzed. RESULTS: Reliability was demonstrated to be excellent as displayed by weighted kappa of 0.960 (95%-confidence interval: CIκw = 0.808-1.112) for the intra-rater reliability and 0.936 (CIκw = 0.749-1.123) for the inter-rater reliability. High correlations of the SULCS with the Fugl-Meyer-Assessment (ρ = 0.889), Action Research Arm Test (ρ = 0.872), and Box and Block Test (ρ = 0.845; all P < 0.001) confirmed a high convergent validity. The longitudinal validity was determined by a moderate to high correlation of the SULCS and Box and Block Test changes (ρ ⩾ 0.695, P ⩽ 0.001). Although floor effects were observed for the SULCS (16%), they were more substantial for the Action Research Arm Test and the Box and Block Test (>38%). CONCLUSION: Due to the good to excellent psychometric properties and the low level of floor effects of the German version of the SULCS, the usage for clinical and scientific purposes can be recommended.

Effects of virtual reality in improving upper extremity function after stroke: A systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: To investigate the effect of virtual reality on arm motor impairment, activity limitation, participation restriction, and quality of life in patients with stroke. To determine potential moderators that affect the efficacy of virtual reality. DATA SOURCES: CINAHL, Medline, PubMed, EMBASE, Cochrane Library, Chinese National Knowledge Infrastructure, and Wanfang Data from inception to October 23, 2021. REVIEW METHODS: Randomized controlled trials that investigated the effect of virtual reality on arm recovery in adult patients with stroke compared to conventional therapy or sham control were included. Physiotherapy Evidence Database Scale was used to assess the methodological quality of each study. RESULTS: Forty studies with 2018 participants were identified. Quality of included studies was fair to high. Virtual reality exhibited better effects on overall arm function (g = 0.28, p < 0.001), motor impairment (g = 0.36, p < 0.001) and activity limitation (daily living) (g = 0.24, p < 0.001) compared with the control group. No significant improvement was observed in participation restriction and activity limitation (specific task). The result for quality of life was described qualitatively. Subgroup analyses demonstrated that immersive virtual reality produced a greater beneficial effect (g = 0.60, p < 0.001). Patients with moderate to severe arm paresis could make more progress after training (g = 0.71, p < 0.001). CONCLUSION: Virtual reality is recommended for improving motor impairment and activities of daily living after stroke and is favorable to patients with moderate to severe paresis. An immersive design could produce greater improvement.

Art skill-based rehabilitation training for upper limb sensorimotor recovery post-stroke: A feasibility study.

OBJECTIVE: The objective of this study was to assess the feasibility of delivering Art skill-based Rehabilitation Training (ART), a novel upper limb motor training program, to patients with stroke as an adjunct to standard care in an inpatient setting. DESIGN: Feasibility study. SETTING: Inpatient stroke rehabilitation unit at a university hospital. PARTICIPANTS: Thirty-eight patients admitted to a stroke rehabilitation unit with upper limb motor impairment were enrolled in the ART program facilitated by trained non-healthcare professionals between December 2017 and June 2021. INTERVENTION: The ART program included nine, one-hour sessions of supervised tracing and freehand drawing tasks completed with both hands. This program was intended to be delivered at a frequency of three times per week over a duration of 3 weeks or for the length of inpatient stay. MAIN OUTCOME MEASURES: Feasibility outcomes included ART program adherence, acceptability, and safety. RESULTS: Thirty-two (84%) participants with subacute stroke completed the ART program and 30 (79%) were included in the study analysis. Participants completed 93-100% of the ART tasks in a median [IQR] of 8 [6-10] ART sessions over a median [IQR] duration of 15 [7-19] days. ART program facilitators effectively provided upper limb assistance to patients with more severe upper limb impairments. Adherence and acceptability were high and no study-related adverse events occurred. CONCLUSION: The ART program was feasible to deliver and highly acceptable to patients with stroke. Further research is warranted to explore the impact of ART on upper limb sensorimotor function and use.

Experiences of augmented arm rehabilitation including supported self-management after stroke: a qualitative investigation.

OBJECTIVE: To explore the experiences of stroke survivors and their carers of augmented arm rehabilitation including supported self-management in terms of its acceptability, appropriateness and relevance. DESIGN: A qualitative design, nested within a larger, multi-centre randomized controlled feasibility trial that compared augmented arm rehabilitation starting at three or nine weeks after stroke, with usual care. Semi-structured interviews were conducted with participants in both augmented arm rehabilitation groups. Normalization Process Theory was used to inform the topic guide and map the findings. Framework analysis was applied. SETTING: Interviews were conducted in stroke survivors' homes, at Glasgow Caledonian University and in hospital. PARTICIPANTS: 17 stroke survivors and five carers were interviewed after completion of augmented arm rehabilitation. INTERVENTION: Evidence-based augmented arm rehabilitation (27 additional hours over six weeks), including therapist-led sessions and supported self-management. RESULTS: Three main themes were identified: (1) acceptability of the intervention (2) supported self-management and (3) coping with the intervention. All stroke survivors coped well with the intensity of the augmented arm rehabilitation programme. The majority of stroke survivors engaged in supported self-management and implemented activities into their daily routine. However, the findings suggest that some stroke survivors (male >70 years) had difficulties with self-management, needing a higher level of support. CONCLUSION: Augmented arm rehabilitation commencing within nine weeks post stroke was reported to be well tolerated. The findings suggested that supported self-management seemed acceptable and appropriate to those who saw the relevance of the rehabilitation activities for their daily lives, and embedded them into their daily routines.

Wristband Accelerometers to motiVate arm Exercises after Stroke (WAVES): a pilot randomized controlled trial.

OBJECTIVE: To evaluate the feasibility of a multicentre, observer-blind, pilot randomized controlled trial (RCT) of a wristband accelerometer with activity-dependent vibration alerts to prompt impaired arm use after stroke. DESIGN: Parallel-group pilot RCT. SETTING: Four English stroke services. PARTICIPANTS: Patients 0-3 months post stroke with a new arm deficit. INTERVENTION: Participants were randomized to wear a prompting or 'sham' wristband during a four-week self-directed therapy programme with twice-weekly therapy review. MAIN OUTCOMES: Recruitment, retention and adherence rates, safety and completion of assessments were reported. Arm recovery was measured by Action Research Arm Test (ARAT) and Motor Activity Log (MAL) without statistical comparison. RESULTS: In total, 33 patients were recruited (0.6 per month/site; median time post stroke: 26 days (interquartile range (IQR):15.5-45)). Baseline, four-week and eight-week median (IQR) ARAT for the control group (n = 19) were 15 (2-35), 35 (15-26) and 31 (21-55) and those for the intervention group (n = 14) were 37 (16-45), 57 (29-57) and 57 (37-57), respectively; for MAL Amount of Use, the corresponding values in the control group were 0.2 (0.0-1.2), 1.1 (0.3-2.9) and 1.2 (0.7-2.9) and in the intervention group were 1.4 (0.5-2.6), 3.8 (1.9-4.5) and 3.7 (2.1-4.3). Four participants withdrew from the study. Wristbands were worn for 79% of the recommended time. The intervention and control group participants received a median of 6.0 (IQR: 4.3-8.0) and 7.5 (IQR: 6.8-8.0) therapy reviews. A median of 8 (IQR: 6-10) prompts were delivered per intervention participant/day. Research assessments were completed for 28/29 and 25/28 patients at four and eight weeks. Eight serious adverse events were reported, all unrelated to the intervention. CONCLUSION: A multicentre RCT of wristband accelerometers to prompt arm activity early after stroke is feasible. A total sample of 108 participants would be required.

The ESCAPS study: a feasibility randomized controlled trial of early electrical stimulation to the wrist extensors and flexors to prevent post-stroke complications of pain and contractures in the paretic arm.

OBJECTIVE: To establish feasibility of initiating electrical stimulation treatment of wrist extensors and flexors in patients early after stroke to prevent muscle contractures and pain. DESIGN: Feasibility randomized controlled trial with economic evaluation. SETTING: A specialist stroke unit in Nottinghamshire. SUBJECTS: A total of 40 patients recruited within 72 hours post-stroke with arm hemiparesis. INTERVENTIONS: Participants were randomized to receive usual care or usual care and electrical stimulation to wrist flexors and extensors for 30 minutes, twice a day, five days a week for three months. Initial treatment was delivered by an occupational therapist or physiotherapist who trained participants to self-manage subsequent treatments. MEASURES: Measures of feasibility included recruitment and attrition rates, completion of treatment, and successful data collection. Outcome data on wrist range of motion, pain, arm function, independence, quality of life, and resource use were measured at 3-, 6-, and 12-months post-randomization. RESULTS: A total of 40 participants (of 215 potentially eligible) were recruited in 15 months (20 men; mean age: 72 (SD: 13.0)). Half the participants lacked mental capacity and were recruited by consultee consent. Attrition at three-month follow-up was 12.5% (death (n = 2), end-of-life care (n = 2), and unable to contact (n = 1)). Compliance varied (mean: 65 (SD: 53)) and ranged from 10 to 166 treatments per patient (target dosage was 120). Data for a valid economic analysis can be adequately collected. CONCLUSION: Early initiation of electrical stimulation was acceptable and feasible. Data collection methods used were feasible and acceptable to participants. A large definitive study is needed to determine if electrical stimulation is efficacious and cost effective.

Outcome measures in post-stroke arm rehabilitation trials: do existing measures capture outcomes that are important to stroke survivors, carers, and clinicians?

OBJECTIVE:: We sought to (1) identify the outcome measures currently used across stroke arm rehabilitation randomized trials, (2) identify and compare outcomes important to stroke survivors, carers and clinicians and (3) describe where existing research outcome measures capture outcomes that matter the most to stroke survivors, carers and clinicians and where there may be discrepancies. METHODS:: First, we systematically identified and extracted data on outcome measures used in trials within a Cochrane overview of arm rehabilitation interventions. Second, we conducted 16 focus groups with stroke survivors, carers and clinicians using nominal group technique, supplemented with eight semi-structured interviews, to identify these stakeholders' most important outcomes following post-stroke arm impairment. Finally, we described the constructs of each outcome measure and indicated where stakeholders' important outcomes were captured by each measure. RESULTS:: We extracted 144 outcome measures from 243 post-stroke arm rehabilitation trials. The Fugl-Meyer Assessment Upper Extremity section (used in 79/243 trials; 33%), Action Research Arm Test (56/243; 23%), and modified Ashworth Scale (53/243; 22%) were most frequently used. Stroke survivors ( n = 43), carers ( n = 10) and clinicians ( n = 58) identified 66 unique, important outcomes related to arm impairment following stroke. Between one and three outcomes considered important by the stakeholders were captured by the three most commonly used assessments in research. CONCLUSION:: Post-stroke arm rehabilitation research would benefit from a reduction in the number of outcome measures currently used, and better alignment between what is measured and what is important to stroke survivors, carers and clinicians.

Effectiveness of electrical stimulation therapy in improving arm function after stroke: a systematic review and a meta-analysis of randomised controlled trials.

OBJECTIVE: The aim of this study is to investigate the effectiveness of electrical stimulation in arm function recovery after stroke. METHODS: Data were obtained from the PubMed, Cochrane Library, Embase, and Scopus databases from their inception until 12 January 2019. Only randomized controlled trials (RCTs) reporting the effects of electrical stimulation on the recovery of arm function after stroke were selected. RESULTS: Forty-eight RCTs with a total of 1712 patients were included in the analysis. The body function assessment, Upper-Extremity Fugl-Meyer Assessment, indicated more favorable outcomes in the electrical stimulation group than in the placebo group immediately after treatment (23 RCTs (n = 794): standard mean difference (SMD) = 0.67, 95% confidence interval (CI) = 0.51-0.84) and at follow-up (12 RCTs (n = 391): SMD = 0.66, 95% CI = 0.35-0.97). The activity assessment, Action Research Arm Test, revealed superior outcomes in the electrical stimulation group than those in the placebo group immediately after treatment (10 RCTs (n = 411): SMD = 0.70, 95% CI = 0.39-1.02) and at follow-up (8 RCTs (n = 289): SMD = 0.93, 95% CI = 0.34-1.52). Other activity assessments, including Wolf Motor Function Test, Box and Block Test, and Motor Activity Log, also revealed superior outcomes in the electrical stimulation group than those in the placebo group. Comparisons between three types of electrical stimulation (sensory, cyclic, and electromyography-triggered electrical stimulation) groups revealed no significant differences in the body function and activity. CONCLUSION: Electrical stimulation therapy can effectively improve the arm function in stroke patients.

Self-directed therapy programmes for arm rehabilitation after stroke: a systematic review.

AIM: To investigate the effectiveness of self-directed arm interventions in adult stroke survivors. METHODS: A systematic review of Medline, EMBASE, CINAHL, SCOPUS and IEEE Xplore up to February 2018 was carried out. Studies of stroke arm interventions were included where more than 50% of the time spent in therapy was initiated and carried out by the participant. Quality of the evidence was assessed using the Cochrane risk of bias tool. RESULTS: A total of 40 studies ( n = 1172 participants) were included (19 randomized controlled trials (RCTs) and 21 before-after studies). Studies were grouped according to no technology or the main additional technology used (no technology n = 5; interactive gaming n = 6; electrical stimulation n = 11; constraint-induced movement therapy n = 6; robotic and dynamic orthotic devices n = 8; mirror therapy n = 1; telerehabilitation n = 2; wearable devices n = 1). A beneficial effect on arm function was found for self-directed interventions using constraint-induced movement therapy ( n = 105; standardized mean difference (SMD) 0.39, 95% confidence interval (CI) -0.00 to 0.78) and electrical stimulation ( n = 94; SMD 0.50, 95% CI 0.08-0.91). Constraint-induced movement therapy and therapy programmes without technology improved independence in activities of daily living. Sensitivity analysis demonstrated arm function benefit for patients >12 months poststroke ( n = 145; SMD 0.52, 95% CI 0.21-0.82) but not at 0-3, 3-6 or 6-12 months. CONCLUSION: Self-directed interventions can enhance arm recovery after stroke but the effect varies according to the approach used and timing. There were benefits identified from self-directed delivery of constraint-induced movement therapy, electrical stimulation and therapy programmes that increase practice without using additional technology.

Hand-Use-at-Home Questionnaire: validity and reliability in children with neonatal brachial plexus palsy or unilateral cerebral palsy.

OBJECTIVE: To investigate construct validity and test-retest reliability of the parent-rated Hand-Use-at-Home questionnaire (HUH) in children with neonatal brachial plexus palsy or unilateral cerebral palsy. DESIGN AND SUBJECTS: For this cross-sectional study, children with neonatal brachial plexus palsy or unilateral cerebral palsy, aged 3-10 years, were eligible. MAIN MEASURES: The HUH, Pediatric Outcome Data Collection Instrument Upper Extremity Scale (neonatal brachial plexus palsy only), and Children's Hand-Use Experience Questionnaire (unilateral cerebral palsy only) were completed. The HUH was completed twice in subgroups of both diagnoses. Lesion-extent (indication of involved nerve rootlets in neonatal brachial plexus palsy as confirmed during clinical observation and/or nerve surgery) and Manual Ability Classification System levels (unilateral cerebral palsy) were obtained from the medical records. Spearman correlation coefficients between the HUH and all clinical variables, agreement, standard error of measurement, smallest detectable change and intra-class correlation were calculated. RESULTS: A total of 260 patients participated (neonatal brachial plexus palsy: 181), of which 56 completed the second HUH (neonatal brachial plexus palsy: 16). Median age was 6.9 years for children with neonatal brachial plexus palsy, 116 had C5-C6 lesions. Median age for children with unilateral cerebral palsy was 6.4 years, 33 had Manual Ability Classification System Level II. The HUH correlated moderately with lesion-extent ( rs =-0.5), Pediatric Outcome Data Collection Instrument Upper Extremity Scale ( rs = 0.6) and Children's Hand-Use Experience Questionnaire ( rs = 0.5) but weakly with Manual Ability Classification System levels ( rs = -0.4). Test-retest reliability was excellent (intra-class correlation2,1 = 0.89, standard error of measurement = 0.599 and smallest detectable change = 1.66 logits) and agreement was good (mean difference HUH1 - HUH2 = 0.06 logits). CONCLUSION: The HUH showed good construct validity and test-retest reliability in children with neonatal brachial plexus palsy or unilateral cerebral palsy.

Home-based Reach-to-Grasp training for people after stroke is feasible: a pilot randomised controlled trial.

OBJECTIVE: To determine feasibility of a randomised controlled trial (RCT) of home-based Reach-to-Grasp training after stroke. DESIGN: single-blind parallel group RCT. PARTICIPANTS: Residual arm deficit less than 12 months post-stroke. INTERVENTIONS: Reach-to-Grasp training in 14 one-hour therapist's visits over 6 weeks, plus one hour self-practice per day (total 56 hours). CONTROL: Usual care. MAIN MEASURES: Action Research Arm Test (ARAT), Wolf Motor Function Test (WMFT), pre-randomisation, 7, 12, 24 weeks post-randomisation. RESULTS: Forty-seven participants (Reach-to-Grasp=24, usual care=23) were randomised over 17 months. Reach-to-Grasp participants received a median (IQR) 14 (13,14) visits, and performed 157 (96,211) repetitions per visit; plus 30 minutes (22,45) self-practice per day. Usual care participants received 10.5 (5,14) therapist visits, comprising 38.6 (30,45) minutes of arm therapy with 16 (6,24) repetitions of functional tasks per visit. Median ARAT scores in the reach-to-grasp group were 8.5 (3.0,24.0) at baseline and 14.5 (3.5,26.0) at 24 weeks compared to median of 4 at both time points (IQR: baseline (3.0,14.0), 24 weeks (3.0,30.0)) in the usual-care group. Median WMFT tasks completed at baseline and 24 weeks were 6 (3.0,11.5) and 8.5 (4.5,13.5) respectively in the reach-to-grasp group and 4 (3.0,10.0), 6 (3.0,14.0) in the usual care group. Incidence of arm pain was similar between groups. The study was stopped before 11 patients reached the 24 weeks assessment. CONCLUSIONS: An RCT of home-based Reach-to-Grasp training after stroke is feasible and safe. With ARAT being our preferred measure it is estimated that 240 participants will be needed for a future two armed trial.

Sensory dynamic orthoses in mild to moderate upper limb tremor in multiple sclerosis: a mixed methods feasibility study.

OBJECTIVE: To explore the feasibility of conducting a Phase III randomized controlled trial evaluating sensory dynamic orthoses for upper limb tremor in multiple sclerosis. DESIGN: Mixed methods: double blind randomized placebo controlled pilot study and semi-structured interviews. SETTING: Rehabilitation centre. SUBJECTS: A total of 21 people with multiple sclerosis with upper limb tremor. INTERVENTIONS: Participants received a sensory dynamic orthosis sleeve or a non-compressive sleeve (placebo) that they wore eight hours a day, for nine weeks. MAIN MEASURES: Outcomes were completed at baseline and nine weeks. The primary outcome measure was the Fahn-Tolosa-Marin (FAHN) Tremor Rating Scale. Secondary outcome measures included the: Action Research Arm Test, Canadian Occupational Performance Measure, Psychological Impact of Assistive Device Scale and the Nine-hole Peg Test. RESULTS: Both sleeves were acceptable, although achieving a good fit was an issue. There were no significant between-group differences for the primary outcome measure. The median ± interquartile range change scores were 0.5 ±6.5 and 2 ±8 for the placebo and treatment group, respectively. The median ± interquartile range Canadian Occupational Performance Measure (performance subscale) demonstrated significant improvements ( p = 0.01) for the placebo group (1.1 ±1.65) compared with the treatment group (0 ±1.2). There was no between-group differences in the satisfaction subscale. The primary outcome measure was sensitive to detect change; however the Action Research Arm Test was not responsive in this study population. CONCLUSION: Undertaking an randomized controlled trial would be feasible and a minimum of 200 participants would be needed for a fully powered, definitive randomized controlled trial.

Utilization of motor imagery in upper limb rehabilitation: a systematic scoping review.

OBJECTIVE: To determine how motor imagery is being delivered in upper limb rehabilitation to guide practice and research. DATA SOURCE: MEDLINE, PubMed, CINAHL, EMBASE, PsychINFO databases were searched from 1987 to November 2014 STUDY SELECTION: English, adults, any clinical population or diagnosis, intervention for upper limb with an outcome measure used. All types of studies were included. Two authors independently selected studies for review using consensus. DATA EXTRACTION: Seven motor imagery elements were extracted using a model implemented in sport research: PETTLEP model (Physical, Environment, Task, Timing, Learning, Emotion, and Perspective). RESULTS: The search yielded 1107 articles with 1059 excluded leaving 48 articles for full review. A total of 38 articles involved individuals with stroke, five articles involved individuals with complex regional pain syndrome, and five articles for other conditions. Motor imagery elements most commonly described were physical, environment, task, and perspective. Elements less commonly described were timing, learning, and emotional aspects. There were significant differences between study populations (e.g. stroke and complex regional pain syndrome) and within populations on how motor imagery was delivered. CONCLUSION: Many of the imagery elements reviewed are not being considered or reported on in the selected studies. How motor imagery is being delivered within and between populations is inconsistent, which may lead to difficulties in determining key elements of effectiveness.

Virtual reality for upper extremity rehabilitation in early stroke: a pilot randomized controlled trial.

OBJECTIVES: To investigate the effect of virtual reality (VR) rehabilitation on upper extremity motor performance of patients with early stroke. DESIGN: Pilot randomized controlled trial. SETTING: Rehabilitation wards. PARTICIPANTS: Twenty three adults with stroke (mean age (SD) = 58.35 (13.45) years and mean time since stroke (SD) = 16.30 (7.44) days). INTERVENTIONS: Participants were randomly assigned to VR group (n=11) or control group (n=12). VR group received nine 30 minutes upper extremity VR therapy in standing (five weekdays in two weeks) plus conventional therapy, which included physical and occupational therapy. Control group received only conventional therapy, which was comparable to total training time received by VR group (mean training hours (SD):VR = 17.07 (2.86); control = 15.50 (2.79)). MAIN OUTCOME MEASURES: The main outcome measure was the Fugl-Meyer Assessment (FMA). Secondary outcomes included Action Research Arm Test, Motor Activity Log and Functional Independence Measure. Results were taken at baseline, post intervention and 1-month post intervention. Participants' feedback and adverse effects were recorded. RESULTS: All participants improved in FMA scores (mean change (SD) = 11.65 (8.56), P<.001). These effects were sustained at one month after intervention (mean (SD) change from baseline = 18.67 (13.26), P<.001). All other outcome measures showed similar patterns. There were no significant differences in improvement between both groups. Majority of the participants found VR training useful and enjoyable, with no serious adverse effects reported. CONCLUSION: Although additional VR training was not superior to conventional therapy alone, this study demonstrates the feasibility of VR training in early stroke.

Core stabilisation reduces compensatory movement patterns in patients with injury to the arm: a randomized controlled trial.

OBJECTIVE: To investigate the effects of adding core stabilisation exercises to traditional rehabilitation in patients with arm injuries. DESIGN: Randomized controlled trial. SETTING: Outpatient clinic. SUBJECTS: Twenty-seven patients with elbow and wrist injuries were randomized to a stabilisation or control group. INTERVENTIONS: The stabilisation group received core stabilisation training and traditional arm rehabilitation and the control group received traditional arm rehabilitation alone for three days/week for six weeks. MAIN MEASURES: Pre- and post-treatment assessments comprising an analysis of compensatory movement patterns and trunk muscle strength as well as functional measurements of the arm, including pain, range of motion, disabilities of arm, shoulder and hand questionnaire and endurance and fatigue severity were performed. RESULTS: Inter-group comparison revealed significantly greater improvements in the degree of mean change (SD) in total compensation (in degrees) of the head (-14.47 (21.65)) and trunk (-5.56 (5.71)) as well as total compensation (-50.02 (48.62)) for the stabilisation group than for the control group (p < 0.05). Increase in trunk muscle strength (2.43 (3.46)) was statistically significant in the stabilisation group compared with the control group. No significant differences were found for functional measures, including pain, range of motion, disabilities of arm, shoulder and hand or endurance and fatigue severity between the groups, although trends towards greater improvement were observed in the stabilisation group. CONCLUSIONS: Adding core stabilisation exercises to traditional arm rehabilitation for patients with traumatic arm injury reduces compensatory movement patterns. Trends towards better functional outcomes in the stabilisation group are worth testing in a large-scale trial.

Effectiveness of constraint-induced movement therapy on upper-extremity function in children with cerebral palsy: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: To systematically examine the research literature on the effectiveness of constraint-induced movement therapy on improving arm function in children with cerebral palsy, and to assess the association between the study effect size and the characteristics of the patients and intervention protocol. DATA SOURCES: A systematic literature search was conducted in PubMed, PsycINFO, Cochrane, CINAHL, Web of Science, and TRIP Database up to May 2014. REVIEW METHODS: Studies employing randomized controlled trial design, children with cerebral palsy, comparing constraint-induced movement therapy with another intervention with a focus on arm function, and upper-extremity measures were included in this review. Methodological quality was evaluated using the Physiotherapy Evidence-based Database (PEDro) scale. RESULTS: The literature search resulted in 27 randomized controlled trial studies with good methodological quality that compared constraint-induced movement therapy with other intervention therapy. Overall, constraint-induced movement therapy provided a medium beneficial effect (d = 0.546; p < 0.001) when compared with conventional therapy. For the subgroup analyses, presence of a dose-equivalent comparison group, intervention location, and time of follow-up were significant factors. Studies examining constraint-induced movement therapy effect without a dose-equivalent comparison group showed a large effect in children with cerebral palsy, but studies with a dose-equivalent group only showed a small effect. Children who received home-based constraint-induced movement therapy had a better improvement in arm function than those who received constraint-induced movement therapy elsewhere. CONCLUSION: The research literature supports constraint-induced movement therapy as an effective intervention to improve arm function in children with cerebral palsy.

Upper Limb Function in People With Upper and Lower Limb Loss 8 Years Postinjury: The Armed Services Trauma Outcome Study (ADVANCE) Cohort Study.

OBJECTIVE: Upper limb (UL) disability in people with UL amputation/s is well reported in the literature, less so for people with lower limb amputation/s. This study aimed to compare UL disability in injured (major trauma) and uninjured UK military personnel, with particular focus on people with upper and lower limb amputation/s. METHODS: A volunteer sample of injured (n = 579) and uninjured (n = 566) UK military personnel who served in a combat role in the Afghanistan war were frequency matched on age, sex, service, rank, regiment, role, and deployment period and recruited to the Armed Services Trauma Rehabilitation Outcome (ADVANCE) longitudinal cohort study. Participants completed the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire, scored from 0 (no disability) to 100 (maximum disability) 8 years postinjury. Mann-Whitney U and Kruskal Wallis tests were used to compared DASH scores between groups. An ordinal model was used to assess the effect of injury and amputation on DASH scores. RESULTS: DASH scores were higher in the group with injuries compared to the group without injuries (3.33 vs 0.00) and higher in people with lower limb loss compared to the group without injuries (0.83 vs 0.00), although this was not statistically significant. In the adjusted ordinal model, the odds of having a higher DASH score was 1.70 (95% CI = 1.18-2.47) times higher for people with lower limb loss compared to the group without injuries. DASH score was not significantly different between people with major and partial UL loss (15.42 vs 12.92). The odds of having a higher DASH score was 8.30 (95% CI = 5.07-13.60) times higher for people with UL loss compared to the uninjured group. CONCLUSION: People with lower limb loss have increased odds of having more UL disability than the uninjured population 8 years postinjury. People with major and partial UL loss have similar UL disability. The ADVANCE study will continue to follow this population for the next 20 years. IMPACT: For the first time, potential for greater upper limb disability has been shown in people with lower limb loss long-term, likely resulting from daily biomechanical compensations such as weight-bearing, balance, and power generation. This population may benefit from prophylactic upper limb rehabilitation, strength, and technique.

Acute hemodynamic responses from low-load resistance exercise with blood flow restriction in young and older individuals: A systematic review and meta-analysis of cross-over trials.

OBJECTIVE: To summarize the existing evidence on the acute response of low-load (LL) resistance exercise (RE) with blood flow restriction (BFR) on hemodynamic parameters. DATA SOURCES: MEDLINE (via PubMed), EMBASE (via Scopus), SPORTDiscus, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, Web of Science and MedRxiv databases were searched from inception to February 2022. REVIEW METHODS: Cross-over trials investigating the acute effect of LLRE + BFR versus passive (no exercise) and active control methods (LLRE or HLRE) on heart rate (HR), systolic (SBP), diastolic (DBP) and mean (MBP) blood pressure responses. RESULTS: The quality of the studies was assessed using the PEDro scale, risk of bias using the RoB 2.0 tool for cross-over trials and certainty of the evidence using the GRADE method. A total of 15 randomized cross-over studies with 466 participants were eligible for analyses. Our data showed that LLRE + BFR increases all hemodynamic parameters compared to passive control, but not compared to conventional resistance exercise. Subgroup analysis did not demonstrate any differences between LLRE + BFR and low- (LL) or high-load (HL) resistance exercise protocols. Studies including younger volunteers presented higher chronotropic responses (HR) than those with older volunteers. CONCLUSIONS: Despite causing notable hemodynamic responses compared to no exercise, the short-term LL resistance exercise with BFR modulates all hemodynamic parameters HR, SBP, DBP and MBP, similarly to a conventional resistance exercise protocol, whether at low or high-intensity. The chronotropic response is slightly higher in younger healthy individuals despite the similarity regarding pressure parameters.

Remote constraint induced therapy of the upper extremity (ReCITE): A feasibility study protocol.

Background: Difficulty using the upper extremity in everyday activities is common after stroke. Constraint-induced movement therapy (CIMT) has been shown to be effective in both sub-acute and chronic phases of stroke recovery and is recommended in clinical practice guidelines for stroke internationally. Despite reports of equivalence of outcome when stroke rehabilitation interventions are delivered using telehealth, there has been limited evaluation of CIMT when using this mode of delivery. ReCITE will (a) evaluate the feasibility and acceptability of CIMT when delivered via telehealth to stroke survivors (TeleCIMT) and (b) explore therapists' experiences and use of an online support package inclusive of training, mentoring and resources to support TeleCIMT delivery in clinical practice. Methods: A prospective single-group, single blinded, study design with embedded process evaluation will be conducted. The study will be conducted at three outpatient services in Sydney, Australia. A multi-faceted therapist support package, informed by the Capabilities, Opportunity, Motivation- Behaviour model (COM-B), will be used to support occupational therapists to implement TeleCIMT as part of routine care to stroke survivors. Each service will recruit 10 stroke survivor participants (n = 30) with mild to moderate upper extremity impairment. Upper extremity and quality of life outcomes of stroke survivor participants will be collected at baseline, post-intervention and at a 4 week follow-up appointment. Feasibility of TeleCIMT will be evaluated by assessing the number of stroke participants who complete 80% of intensive arm practice prescribed during their 3 week program (i.e., at least 24 h of intensive arm practice). Acceptability will be investigated through qualitative interviews and surveys with stroke survivors, supporter surveys and therapist focus groups. Qualitative interviews with therapists will provide additional data to explore their experiences and use of the online support package. Discussion: The COVID-19 pandemic resulted in a rapid transition to delivering telehealth. The proposed study will investigate the feasibility and acceptability of delivering a complex intervention via telehealth to stroke survivors at home, and the support that therapists and patients require for delivery. The findings of the study will be used to inform whether a larger, randomized controlled trial is feasible.

Evaluating the clinical decision making of physiotherapists in the assessment and management of paediatric shoulder instability.

OBJECTIVE: To elicit what information and clinical decision-making processes physiotherapists use in the assessment and management of paediatric shoulder instability. DESIGN: Qualitative study. A modified nominal focus group technique, involving three clinical vignettes, was used to elicit physiotherapists' decision-making processes. SETTING: Physiotherapy departments from across four separate clinical sites. SUBJECTS: Twenty-five physiotherapists, (18F:7M), ranging from two to 29 years post qualification. OUTCOMES MEASURES: Thematic analysis. The initial round of coding was used to draw up a quantitative assessment of the diagnoses and map information used for clinical decision-making against the International Classification of Functioning (ICF) framework. RESULTS: The themes identified related to 'Differences in diagnoses, classification and diagnostic processes', 'Diagnostic process occurs over a long period of time', 'Management and prognosis are influenced by a number of factors' and 'Diagnostic test choices and prognosis influenced by factors beyond the patient injury'. CONCLUSION: Current methods of assessment are prone to bias and error and may lead to inconsistent or delayed provision of essential care. Further work is needed to develop methods of measurement and frameworks which can accurately identify relevant physiological mechanisms and personal factors associated with shoulder instability as a part of the assessment/diagnostic process.
